Software Installation Prerequisites

Before you begin the software installation, ensure that these procedures are complete:

  • You used Oracle Exadata Deployment Assistant to generate the configuration files. See Using Oracle Exadata Deployment Assistant.

  • You assembled the installation files into the WorkDir directory under the OneCommand installation directory. (The OneCommand installation directory is the directory to which you extracted the OneCommand ZIP file, such as linux-x64.)

  • The checkip script ran successfully with no remaining errors.

  • All racks of a multirack installation are cabled together. See Extending a Rack by Adding Another Rack.

  • All components of all new racks are configured. See Configuring a Recovery Appliance Rack.

  • Oracle Management Server is operating on the same network as Recovery Appliance.

  • Reclaim the disk space on all compute servers. See "Reclaiming Disk Space on the Compute Servers".

  • The Oracle tape library is installed and operational. A tape library is an optional component of Recovery Appliance.

About Adding a Rack to an Existing Rack

When you add a new Recovery Appliance rack to an older rack, the factory installed images are typically different. You can either update the older rack to the new image, or retain the older version and reimage the new rack to match it. In either case, ensure that all servers and all Sun Datacenter InfiniBand Switch 36 switches are at the same patch level.

About Adding New Storage Servers to an Existing Rack

Additional patching considerations include the Grid Infrastructure and database home releases and bundle patch updates. If the software installation applies new patches, then Oracle recommends changing the existing servers so the new servers inherit the releases as part of the extension procedure. This way, the number of servers that require patches is lower. Apply any patches to the existing servers in advance, so that they are at the desired level when the extension work is scheduled, thereby reducing the amount of work required by the extension.
